Do any of you have any experience using Devcon Plastic Welder glue/adhesive, as opposed to standard epoxy, to repair leaks in your coolant bottle? I tried epoxy but it didn't hold for very long. I've heard that the Plastic welder sticks well to polyethylene/nylon so I'd like to try the Devcon product. I know that I should go ahead and replace the reservoir (yet again!) but just seeing if any of you have had luck repairing tiny cracks with products like these. The crack that I have is a really tiny perforation and accessible without removing the tank, ignition or airbox. Figured its worth a shot!
